I remembered hearing a while ago about, in theory, that you could model the game forever and it just about the time and resources. So to put that point into a suggestion I would say Bristol - Paignton. Why I say this is because you have beautiful scenery from the rolling hills of Somerset to the Dawlish sea wall in Devon. You also get a mixture of: Express, fast commuter, slow commuter and freight. You could utilise the HST as either the castle class or the proper express version. The 166 could be used between Bristol and Taunton with Weston-super-mare as some destinations. This would be a chance to put the 800 in the game as well with the HST being used as a castle class. These new additions to the game could extend to the 150/2 and/or the 143 as they were used along the Exmouth branch (which could be a nice addition just like the Barnstaple branch, wink wink nudge nudge). The 66 would be used for the odd freight that goes down towards Plymouth from Taunton (Westbury). As much as this is a good idea I don't think it would happen. I don't think DTG would want to make a route this big and this extensive. There's always hope though. Even if it is miniscule.
